solved it’s a problem with PHP 7.1

hm ok but then everytime the content changes i have to rebuild the whole sites and posts where i have used the template

isn’t there a way to put a page’s content to the footer.php with a hook or something so that i don’t have to take the whole footer.php

hi the site is local, i have the settings
sidebar right side
Page Sidebar Navigation checked

The Page Sidebar is empty
So if i have a page with Children the sidebar right gets Displayed the Children of the Page
If i have a Page without Children the Default Sidebar gets Diplayed (Pages/Categories/Archive)
If i add a widget to the page sidebar this gets displayed
But i want to hide the Sidebar completely if there are no Children (i can do this by the options of the Page)

but original WP uses category/taxonomy
or “slug”/taxonomy
isn’t it possible to use a other slug + portfolio taxonomy for the portfolio categories?

.av-masonry .av-js-disabled a {visibility: visible; opacity: 1;}
in Quick css solved the problem for me
